Detailed Description

The invention will be further described with reference to specific examples, which are intended to be illustrative only and not to limit the scope of the invention. Furthermore, it should be understood that various changes and modifications of the present invention may be made by those skilled in the art after reading the teachings of the present invention, and such equivalents also fall within the scope of the appended claims.

Referring to fig. 1, fig. 2, fig. 3, it includes detector box 1, the fixed surface of detector box 1 installs protective housing 2, the fixed surface of protective housing 2 installs handle 3, protective housing 2's left end articulates there is guard gate 4, locking device 6 is installed to protective housing 2's left side lower extreme, controlling means 7 is installed on protective housing 2's lower surface left side, protective housing 2 and guard gate 4's inside fixed mounting has buffer 5, buffer 5 includes even fixed mounting at protective housing 2 and the inside bumping post 51 of guard gate 4, bumping post 51 is the cavity design, the space packing between bumping post 51 has buffering fragment 52.

The cooperation of controlling means 7 and locking device 6 can carry out switch locking control to guard gate 4, protective housing 2, only can open and shut control through controlling means 7, and other external forces can't be opened, and buffer 5 can offset the external force that receives in the deformation process of inside through the cooperation of inside buffering fragment 52 and cushion post 51, reduces the destruction of external force impact to inside detector, and the protective capacities is strong.

Locking device 6 includes that the locking of fixed mounting at the lower extreme of guard gate 4 right side colludes 61, and the right-hand member that the locking colluded 61 is the inclined plane design, and the low right side height in a left side, and rectangular channel 62 has been seted up to the left side lower extreme of guard box 2, and rectangular channel 62's lower surface left side fixed mounting has joint piece 63.

The locking hook 61 can be clamped inside the control device 7 when the protective door 4 is closed, and the clamping block 63 can reversely limit the clamping rod 71, so that the clamping rod can only rotate in one direction and brake in the reverse direction, and the clamping is firmer.

The control device 7 comprises a through hole 72 formed in the left side of the lower surface of the protective box 2, a clamping rod 71 is inserted into the through hole 72, a button 74 is fixedly mounted at the lower end of the clamping rod 71, one end of a spring 73 is fixedly mounted at the upper end of the button 74, the other end of the spring 73 is fixedly mounted on the left side of the lower surface of the protective box 2, and the spring 73 is sleeved on the outer surface of the clamping rod 71.
